Of course it lacked the mark on the anticommunism checkbox, but control of society and control of economy were checked. That's 50% of the fascist playbook.
There was probably some nationalism too. Stalin buried internatonalism quickly. They would inevitably bow to the Russian overlords. No shame about it. We were bowing to the USA in the West and we still are.
Anyway, was communism only a facade by the 70s and the 80s? In that case it was a fully fascist country. All of the East.
I'd like to hear from somebody who lived in those countries at that time.
